Переведите текст, обратив внимание на безличные и неопределенно-личные предложения и способы их перевода. THE RUSTING OF METALS It has long been known that metals can pass from a metallic to an earthy form. One must be careful not to expose unprotected iron to the open air, as under the influence of atmospheric conditions the outer layer of the iron quickly changes into a reddish crust called the rust. One can easily find that this new material is a different substance from iron. The rust is very brittle, it is much lighter, bulk for bulk, than iron and it is not attracted by a magnet. It was early observed that, although the specific gravity of the earthy product was less than that of the metal, yet there was a much greater bulk of it, and that, in fact, the earthy material weighed more than the original specimen of the metal. It was Lomonosov who first proved that the extra material came from the air. He placed some tin in a flask and sealed up the mouth of the vessel. The tin was heated and converted into the white powder. Upon weighing the apparatus it was found that no change in weight occurred. It turned out, however, that when the mouth of flask was opened, a good deal of air rushed in and the total weight was then greater. A portion of the original air had joined itself with the tin to form the powder. Eighteen years later the same experiment was made and the same conclusion drawn from it by Lavoisier. He named the gas taken from the air, oxygen. It is possible to confirm these conclusions in various ways. For example, when the air is pumped out of the flask before it is sealed, the metal can be heated in the vacuum indefinitely without rusting. Thus it can be seen that fundamentally rusting is the process in which metals oxidize and form compounds. It has been estimated that more than 25 per cent of the annual production of iron in the USA is consumed in replacing other iron that has been rendered unserviceable by rusting. It is necessary, therefore, to wage a constant battle against this chemical process and our immediate concern is how to take care of metallic devices and structures once they enter our possession. We try to prevent or reduce rusting by various means, such as electroplating, painting or otherwise treating the metals that are susceptible to attack by the agencies of this harmful action.

Переведите текст, обращая внимание на модальность: EQUILIBRIUM With what can we associate the word “equilibrium”? We ought to know that the term applies equally well to a motor-car moving along a straight road at a constant speed. From a scientific point of view an object can be in equilibrium not only when it is standing motionless, but also when it is moving in a straight line at constant speed. On the other hand it would not be in equilibrium if it were increasing speed or slowing down or provided it were going around a corner. Evidently, when there are no forces pulling or pushing a body, that body must always be in equilibrium. However, objects with forces acting on them may also be in equilibrium. But, then, the forces must balance; that is, their vector sum is to equal zero. Thus, in the case of the speeding automobile there are forces acting, but they balance each other in pairs. The pull of gravity downward is counteracted by the push of the road upward. The driving force supplied by the motor is balanced by air resistance and other frictional forces. However, as the driving force supplied by the motor is greater than the frictional resistance, the car is accelerated. But sometimes an object may not be in equilibrium even though the vector sum of all the forces is zero. It may have a tendency to rotate unless all the forces are applied at a single point, or unless the tendency to rotate in one direction balances the tendency to rotate in the opposite. Thus the second condition for equilibrium is that the tendency to rotate should be zero. There are always two requirements for equilibrium: first, the vector sum of all the forces acting on a body should be zero; and, second, there must be no tendency to rotate, that is, the tendency to rotate the body in one direction must be balanced by the tendency to rotate it in the opposite direction. We have to point out the importance of equilibrium in any engineering design and construction. For example, if a house is to stand, each of its parts must evidently be in equilibrium.

Rethinking work Across the planet, the shrinking of opportunities to work for decent pay is a crisis yet to be faced. In the end, the job crisis raises the most fundamental question of human existence: what are we doing here? There is a colossal amount of work waiting to be done by human beings – building decent places to live, exploring the universe, making cities less dangerous, teaching one another, raising our children, visiting, comforting, healing, feeding one another, dancing, making music, telling stories, inventing things, and governing ourselves. But much of the essential activity people have always undertaken to raise and educate their families, to enjoy themselves, to give pleasure to others, and to advance the general welfare is not packaged as jobs. Until we rethink work and decide what human beings are meant to do in the age of robots and what basic economic claims on society human beings have by virtue of being here, there will never be enough jobs. – From “The end of jobs”, by Richard J. Barnet, senior fellow at the Institute for Policy Studies, in Harper’s magazine, September 1993.
